Skipping frames at start of alarm

[AlphaSupreme]

I'm running zoneminder 1.30.0 on an odroid C2 with ubuntu 16.04.
Everything works fine, and with one camera the load is between 1 and 2.

The thing is, when an alarm starts a few frames are skipped in the recording.
The first 25 frames go fine, then the reason the alarm is triggered happens, losing a few frames, after that the recording is fine.
I already disabled the "CREATE_ANALYSIS_IMAGES" option and lowered the analysis FPS.

Any ideas?

I've found this to be a result of inadequate buffers for your source.

On the buffer tab for your cam that's dropping frames make sure that the Image Buffer Size (frames) is at least the sum of Warmup Frames + Pre Event Image Count + Post Event Image Count.

This eats into /dev/shm so keep an eye on that.

This solved a long standing issue I was having at our site. Thank you for the information!
